[...] Hi, the reasoning is that usually focus is not given to the direct child of a scrolled window, but to another grandchild. This usually makes sense so that when using keynav and tabbing from widget to widget inside a scrolled area, the scrolled window will automatically adjust itself to reveal the new button/entry/widget which may otherwise be hidden (so the user doesnt end up having to manually move the scrollbars to see what widget is focused). For your case, you should be able to opt out by simply clearing the focus adjustments with the gtk_container_set_focus_[v/h]adjustment() APIs.
